Huntington Ravine wildflower id help please

[forestgnome]

My wildflower guides don't have the following...

This image, with two different wildflowers, is from just below the fan. I thought the bright yellow flowers are a ragwort but not sure, and what are the little purple ones?

ragwort?

???

These remind me of flox. They are six feet tall...

All three are living near just below the steepest part of the headwall. BTW, there's also nice harebells up there...

Thanks for any help

Ragwort

Yes, they are Ragwort. There may be some other word before Ragwort like Round-leaved or Robbins, I'm not sure of the exact type, but they are definitely Ragwort. It is toxic to all livestock and humans. The tiny purple ones I don't know, maybe Speedwell? but only a guess. The tall ones look like Fireweed to me.
